Part Number : RM6222D
Function : Dedicated current mode PWM controller
Package : DIP 8 Pin Type
Manufactures : Mediatek
RM6222D combines a dedicated current mode PWM controller with a high voltage power MOSFET. It is optimized for high performance,low standby power ,and cost effective of f-line flyback converter applications in sub 20W range. RM6222D of fers co mplete protection coverage w ith automatic self-recovery feature inclu ding Cycle-by-Cycle current limiting,over load pr otection,VDD over voltage clamp and under volt age lockout. Excellent EMI performance is achieved with freque ncy shuf fling technique together with sof t switching control at the totem pole gate drive output.
